Abstract: To regenerate a diesel particulate filter (10) which traps particulate matter contained in the exhaust gas of a diesel engine (20), a controller (16) raises the temperature of the exhaust gas through fuel injection control of a fuel injector (23), and thus burns the particulate matter trapped in the filter (10). The controller (16) controls the fuel injector (23) to raise the temperature of the exhaust gas to a higher temperature as the amount of particulate matter trapped in the filter (10) decreases, thereby-realizing effective regeneration while preventing the temperature of the filter (10) from becoming excessively high.

Abstract: A regeneration control device, which regenerates a filter (13) for trapping particulate matter in exhaust gas from an engine (1), is disclosed. The filter (13) supports a catalyst which oxidizes unburnt components in the exhaust gas. The regeneration control device has a temperature sensor (14) which detects a filter inlet exhaust gas temperature (Tdpf_in_mea); and a microcomputer (22). The microcomputer (22) is programmed to compute a filter outlet exhaust gas temperature (Tdpf_out_cal), not including temperature rise due to oxidation reaction of unburnt components based on the detected inlet exhaust gas temperature; compute the filter bed temperature (Tbed_cal) based on the detected inlet exhaust gas temperature and computed outlet exhaust gas temperature; compute a temperature rise (?Thc1) due to oxidation reaction of unburnt components; correct the bed temperature based on the computed temperature rise (?Thc1).

Abstract: A diesel engine (1) comprises an exhaust passage (3), and a DPM filter (4) provided on the exhaust passage (3), which traps diesel particulate matter (DPM) contained in the exhaust gas such that the diesel particulate matter accumulates therein. An engine controller (11) starts regeneration processing of the DPM filter (4) by raising the exhaust gas temperature when a regeneration timing of the DPM filter (4) is reached, sets a target exhaust gas temperature during regeneration processing to ensure that the temperature of the DPM filter (4) does not exceed an upper temperature limit of the DPM filter (4), even when the temperature of the DPM filter (4) is raised due to the engine (1) entering an idling condition during the regeneration processing, and controls the exhaust gas temperature to the target exhaust gas temperature.

Abstract: A regeneration control device which regenerates a filter (13) by increasing an exhaust gas temperature to burn exhaust gas particulates trapped in the filter, is disclosed. The filter (13) traps particulate matter in exhaust gas from an engine (1). The regeneration control device suppresses fuel cost-performance impairment due to filter regeneration. The regeneration control device has a load detection sensor (31) which detects an engine load and a microcomputer-based controller (22).

Abstract: To regenerate a diesel particulate filter (10) which traps particulate matter contained in the exhaust gas of a diesel engine (20), a controller (16) raises the temperature of the exhaust gas through fuel injection control of a fuel injector (23), and thus burns the particulate matter trapped in the filter (10). The controller (16) cumulatively calculates the time during which the temperature of the filter (10) exceeds a target temperature as an effective regeneration time. By estimating the amount of particulate matter remaining in the filter (10) on the basis of the effective regeneration time, the controller (16) estimates the amount of remaining particulate matter with a high degree of precision and without consuming energy, whereupon regeneration of the filter (10) through fuel injection control ends.

Abstract: A filter (10) which traps particulate matter contained in the exhaust gas of a diesel engine (20) for a vehicle is regenerated by fuel injection control. A controller (16) calculates a representative value of the operating condition of the diesel engine (20) during a latest predetermined time period, and determines the traveling condition of the vehicle on the basis of this representative value. When the representative value corresponds to a highway traveling condition, fuel injection control is performed in accordance with a pattern for burning all of the particulate matter trapped in the filter (10). Under any other conditions, fuel injection control is performed in accordance with another pattern. Hence optimum filter regeneration can be performed depending on the traveling condition of the vehicle.
